Did you use a de-telecining filter or a de-interlacing filter?

The MPEG2 was interlaced; I deinterlaced to produce the MPEG4.

I have recently begun to experiment with the "pullup" and "filmdint" filters in mencoder that are designed to handle telecined video. (In 30fps telecined video, the pattern is 3:2; three progressive frames followed by 2 interlaced frames.)

These filters are supposed to be able to analyze the film and restore the original 24fps progressive video without the degradation that simple de-interlacing causes.

I haven't had much success so far. (Perhaps it's because the films being processed are so blurry, scratchy, and dirty.) Sometimes interlacing remains, and often motion becomes jerky in spots (as though frames are dropped).

AFTER EFFECTS does "inverse telecine" best - and DVD Architect makes the best DVDs from such files, encoded at 24fps with the DVD player instructed to introduce pulldown.

Downside: Some operator experience and knowledge is required.

I've never tried de-telecining. Handbrake, the encoder I use most often, will inverse telecine using a filter from the MPlayer project. From what I've read it does the job well. When combined with the decombing filter, all artifacts are said to be removed. I'm going to try this sometime on one of the 30fps MPEG2s that shows interlacing artifacts and see how well it does.

Since mplayer and mencoder are part of the same package, Handbrake probably uses one of the filters I've been experimenting with.

Since poor video quality must make it harder for the reverse telecine filter, I went through some of my DVDs and found one with decent video and telecined content. (I think it was sourced from VHS tape.) Most DVDs are 24000/1001 fps progressive.

The filter "filmdint" seems to have done a perfect job on the first 6 minutes of the movie. No interlacing, no jerkiness, and the audio is in synch.

It's really gratifying to undo the mangling that was done while converting to 30000/1001 fps and to restore the clean, progressive 24 fps source.

That's great! Those that have described getting excellent results with inverse telecining/decombing filters in Handbrake were working with DVD images.

I certainly appreciate your feeling gratified in producing video equivalent to the original film. I doubt that many old movies would be available now though, nor would I have acquired a love of old movies if I hadn't been for TV broadcasts. As technology improves I imagine telecining and interlacing will disappear, and these old movies will be obtainable as originally made.

I inverse telecined and decombed the MPEG2 of King of the Zombies, and it looks great - No visible interlacing, and no stutter in motion either. The frame rate is 25fps. Must have been PAL. I'll redo it to produce an avc/aac file and upload it if it still looks good.

There may be problems with doing this with other MPEG2s here though, because so many have missing frames, and that might mess up the inverse telecining.

The inverse telecined, decombed, and gray-scaled (to remove the greenish cast in the source) avc/aac MPEG4 looks and plays fine. The only aberrations I noticed corresponded to those in the source.

The frame rate given below for the MPEG4 is 25.313fps. It should be 24fps, if 100% of the MPEG2 was inverse telecined. 18,786 frames (15.55%) were removed through inverse telecining. 20% would be expected to be removed if 100% of the MPEG2 was inverse telecined, so the inverse telecining was 77.75% effective. Hence, 77.75% of the MPEG4 is at 24fps, and 22.25% is at 29.970fps, yielding a value of 25.328fps.

Here are the details for the MPEG2 and MPEG4 files:
